Problems reading NB temperature - Pegatron m2n78-la

This problem has been stumping me for the last couple weeks. Some background to begin with: (you can skip to the >>>> if you're not interested, it is mostly unnecessary) I started messing around with my friend's computer when I found out she was interested in doing some major performance upgrades. I installed some temperature monitoring programs, and found that speedfan reported the northbridge temperature as 117 degrees -- Celsius. I dismissed it as a program/sensor error and told her to not worry about it--I couldn't believe any chip would run that hot, idle. A few days later, it started worrying me that I may have dismissed the problem too soon; I took off the case and touched the heatsink, and sure enough, it seared my finger in less than a second. I rummaged around in my box and found a suitable new heatsink, much beefier and taller than the old one, did some slight modifications and put on the new heatsink with AS5. The temps dropped to normal ranges, something like 45C idle, 60C furmark load. For good measure, I put on a little Asus blower fan and the temps dropped further to something like 38C idle 45 load. Now, I want to note that although the new heatsink certainly had much more surface area, and was taller, I feel that a good portion of the problem was the TIM on the stock HS; it was that pink gluey thermal adhesive stuff. It was browned around the chipset mounting area, and the foam pads around the HS were dark brown (usually they are white-ish). >>>>>>>>>>>>>>>>>>>>>>>>>>>> Fast forward a few days later, I install an 8800GT from [H] FS/FT, only to find out that the accelero s1 causes clearance issues with the NB heatsink. I have to remove the beefier heatsink and put on the stock one again, this time with some quality paste. I figured it would be okay because the new video card would take the video processing load off of the NB, and the new TIM on the NB would do its part to keep the (previously way too hot) part cool. I would just do a quick check of idle and load temperatures, and be satisfied that the NB couldn't cook my breakfast any longer. I load up Vista, and to my dismay find that the temperature sensor for the northbridge is no longer being detected, neither by Speedfan nor HWmonitor. Instead, it has been replaced by the 8800GT core temperature. How can I retrieve the NB temperature? I know there's a sensor on the chip, but I guess it was disabled along with switching the video processing over to the gpu (or something)? I'd like to find out to make sure the thing isn't cooking itself. Anyway, the system in question is an HP pavilion a6720f. The mobo is a PEGATRON m2n78-la, it is made by Asus for HP, and not supported by Asus (at least to the extent that Asus PC Probe II refuses to run). a thorough user manual of the board can be found here, and here are specs

In speedfan go into the config. it will list all the sensors the program can read. there you will see the sensor. you can move it up in the list so it shows up in the window. though because it was reporting 117C im going to say it was a dead sensor/no sensor. or your looking at the wrong sensor in t...

I would suggest using HWiNFO for sensors and post a screenshot of that.

I don't know how hot the new athlons run, but that'd be too hot for me. Maybe try reseating the Heatsink.

I am running the asus a8n-e ultra board and with the stock cooler which is a cheap cooler it ran at 40-50 deg celcius.I took a zalman d47 passive heatsink and cut off thetop fins so they are all level across the top and installed a 40mm fan on it.my temps now are 32-36 deg celcius.this is measured w

I'm trying to keep my pc as quiet as possible, and the second-loudest fan (stupid stock 6600gt fan is the loudest... I'll pick up a vf700-cu when I upgrade) is the NB cooling on my DFI nf4 ut-d. I can control when the fan should turn on, and I think I have it at 55c now and it rarely gets this hot,...
I tend to not trust temp probes too much, so I don't have much faith in the mobo turning fans on/off for me. I would set it to turn on a bit earlier, if nothing else for oc stability and piece of mind. If you can find a way to have a nice quiet 120mm fan blow on/across the chip, that would help alot

Hi all I have been running at 235 FSB for about a week, however after I installed my NB-1C I have had problems.

I just bought my new Asus Rampage II Extreme( I previously had Asus P6T Deluxe V2, but somehow I accidentally bent one pin of the CPU socket, so naturally I fry the board).

Galta said:+5V being 4.97 is very good. You are less than 1% below. As of your temps, I need further info: - what's the ambient temperature? - what is your CPU core revision? If you have had the CPU for long enough, it could be a C0, much hotter than a D0. Anyway, my own personal experience with V1

I just built my first computer and I'm curious about the temperature on the northbridge. According to ProbeII, it's the highest temperature on the motherboard. It idles at around 62°C which seems high to me for idle. Now, I am quite new at this, so is that normal for an idle temperature? A friend o...
That seems high to me, but if it's working it shouldn't be a big deal. I also have a Crosshair IV, and I've heard that a number of people have had trouble with the standoffs for the northbridge being the wrong height. You might want to google "Crosshair IV northbridge temperature" and see what On

I suggest removing the HSF on the NB, cleaning it and applying a proper Thermal compound.

There is a options menu some where to allow turning off certian temps/voltage readings. looks like he just enabled them from this menu. sorry i have the board or software, i do know that the option is in there. shouldnt be that hard to find though.

Probably the easy tune. The brisbane's temp readouts are weird. My BIOS and the biostar util are really the only ones that read the temp correctly on mine as well.

Idk why but my gpu which is a sapphire hd radeon 7750 is reading the wrong temperature, it says its idling at 9C which is 48 degreese LOL. so does anyone else have trouble like this and know how to fix it?...
HWMonitor doesn't show your 7750, I see only HD 8570D which must be your APU. How 'bout you scroll up a little?
